Encore CS4 Blu-Ray and Real 1080p 30ish frame rates

Is this really true that Encore CS4 and prior only supports 1080p in 24ish frame rates? Is 1080p 30ish not an official Blu-Ray frame rate? I have not seen any significant threads that really question why it is not there. With most good prosumer and pro cameras supporting 1080p 30's...I just would have assumed Adobe could conform to a seemingly strong standard.

thanks for anyone's insight into this gripe or my failure to understand the format.

(I hate the thought of converting my pristine 1080p 30's to 24's)

OK...results of 30 to 24 conversion are far worse than I imagined...
Choppy movement and the impression of dropped frames through the whole Blu Ray disk.
Somebody out there knows how to render 1080p 30's to Blu Ray in Encore...speak up!

Blu-ray only supports 24p, 50i and 60i. You can compress 30p video in a 60i stream. It will still look like 30p on playback because there is no temporal shift between fields. This is sometimes referred to as "Psf" (progressive segmented frame) because the progressive frames are broken up and delivered in two fields instead of one frame. You definitely don't want to convert 30p to 24p as even the very best frame rate converters will cause a big reduction in quality and smoothness. Just pretend it is 60i when you compress it.
